Miami Dolphins DL Kheeston Randall and DE Derrick Shelby have stood out in training camp and the preseason, and appear to be headed for roster spots. Randall tipped an interception in practice, and Shelby had two sacks in the team's first preseason game against the Dallas Cowboys. "I love him because he gives effort, he's in the spots where he's supposed to be," head coach Joe Philbin said.
